I am Graham Mitchell, a software engineer for Vrbo (née HomeAway) in Austin, TX. I am also the author of the books "Learn Java the Hard Way" and "Learn Object-Oriented Java the Hard Way".
My wife has a PhD in nutrition science and is also a registered dietitian. She taught nutrition at the University of Texas for many years but now teaches only at Austin Community College. She is much happier there.
Prior to becoming a software developer, I spent twenty years teaching Computer Science at Leander High School -- from 1997 through 2017.
The high school I taught at is a pretty good school; consistently ranked near the top 5% of public schools nationally. I had a lot of students who are exceptional but most of my students were regular kids with no particular aptitude for programming. I taught over 2000 students.
